MAST Scenarios

• Updates are at Local Discretion• You may Update 2017 or 2025 or Both• 2025 Strategy should achieve Final Target for TN

– It’s Not Possible to Meet Target for both TN and TP– If it Doesn’t the State will Supplement the Strategy– If Sector Targets are not met Individually, Narrative

Strategy Needs to Explain• 2017 Strategy Target Now 60% (was 70%)• Submit to State the same way as in November

2011• Please Do Not make changes after submittal date!

– Save under a different name before changing anything

5

Narrative Strategies

• Updates are at Local Discretion• Opportunity to Account For:

– Extension from 2020 to 2025 (Planning Horizon)– 60% 2017 Target (rather than 70%)– Insights from Public Review Process– Outcomes of the 2012 General Assembly

• Reductions• Resources & Funding Plans• Tracking, Reporting & Verification• See Guidance Under “What’s New” WIP II

Webpage

6

Local 2013 Milestones

• Updates are at Local Discretion• Considerable Flexibility in Local 2013 Milestones • Local 2015 Milestones More Rigorous• BMP Implementation Milestones:

– July 1, 2011 – June 30, 2013– Consider Pace to Reach Long-Term Targets– Acceleration in 2015 Milestones

• Programmatic Milestones:– January 1, 2012 – December 31, 2013– Consistent with Narrative Strategy– Consider New State Legislation

Nitrogen vs. Phosphorus • The current approach is designed to increase BMPs

implementation levels to meet the regulated urban and non- regulated urban targets within the sector and at the county scale

• Because bmp efficiencies are different for N and P, the “level of effort” required may differ for each pollutant within a county

• The scenario development approach applies the level of effort to meet the more stringent of N and P

2017 Developed Land Scenario

• Scenario development rules– If a county/sector did not provide a scenario

• Meet MS4 retrofit goals• Urban nutrient management and forest buffers on non-

regulated

– If a county/sector provided a scenario then it was not modified

• Assumes commitment to meet the 2025 target• State must meet 60% of statewide goal by 2017

19

2025 Developed Land Scenario

• Goal– Add BMPs to meet countywide urban target, for both N

and P

• BMPs applied based on E3 (consistent with allocation process)– Forest Buffers– Filtering Practices– Impervious Surface Reduction– Urban Nutrient Management– Erosion & Sediment Control

Septic System Strategy

Septic Strategy 2017

• If a county provided a 2017 septic strategy the scenario was used

• If a county did not submit a 2017 septic strategy then denitrification was applied to 60% of the critical area. This is based upon the assumption used in the Phase I WIP

Notes:• Three step approach uses the

25

Modeling, Moving Forward• What are we hearing from teams?

– Landuse– Accounting– Understanding regional differences

• What are we doing?– Listening and– Working with the partnership to address these concerns

• Midpoint reevaluation– 2017– December 2015 - Fully calibrated and operational Watershed Model

and Bay Model ready for analysis of Phase III WIPs.

Copying the WIP Strategies

• MAST Scenarios - “2025 Statewide WIP Scenario and 2017 Statewide WIP Scenario”

• In the MAST navigation menu select “Add Scenario”.

28

Copying (continued)

• Add New Scenario screen [screenshot on next slide]:– Enter a name and description for your new scenario.– Select 2010 as the landuse year.– Select a geographic scale and area (“State” to copy the entire Maryland

WIP scenario, or “County” to capture a particular county).– Select the Wastewater strategy (“2017 Loads” for the 2017 WIP

scenario; “Cap Load” for the 2025 WIP scenario)– Select option for “All BMPs, including Maryland specific”– Under “Please select the scenarios you would like to copy BMPs

from:” choose from the drop-down the scenario to be copied (2025 Statewide WIP Scenario and 2017

– Statewide WIP Scenario). Select this scenario for all BMP choices.

Future StepsFuture Steps

35

Continued Local Engagement• See Section 4 of Phase II WIP: “Future Steps”• Quarterly Contact (EPA/State and State/Local)

– Webinars– Face-to-Face Meetings– Annual Regional Meetings

• Promote continual implementation progress– Monitor Progress & Challenges on Local Milestones

• Programmatic Capacity Building key for 2013 Evaluation– Assistance: Help Maintain Progress

• Answer Questions, Provide Guidance• Joint Problem Solving

– Creative paths to success, Near-term & Long-term• Watershed Assistance Collaborative (Technical & Funding)

36

Continued Local Engagement

• Tracking, Reporting and Verification– Accounting is Critical to Demonstrating Progress– Local & State Processes are being Refined– EPA Initiative on Verification– Near-Term: Focus on 2013 Milestones

• State Initiatives:– Offsetting Growth in Loads– Evaluate Max Feasible Implementation (E3) &

Implications for Pace of Implementation– Rural Residential Reforestation– Urban Nutrient Management

37


• Offsetting Growth in Loads– Fully implementable growth offset program by

the end of 2013 – Offset Stormwater and Septic Loads– Draft Offset Policy Review Process:

• Draft Policy is Undergoing State Interagency Review• Present to BayStat on May 29• Present to the WIP Workgroup of the Maryland

Sustainable Growth Commission (Date TBD)• Extensive outreach with stakeholders

38


• Model & Data Refinements– Addressed in Previous Presentation

• 2015 Milestones– Begin development in beginning of 2013– Due to EPA at end of 2013
